Here’s one for the greenies out there, it’s a solar iPhone 4 case. I’m not quite sure though if an hour of charging is worth only 25 minutes of additional talk time. I guess it could be if you really need it. I don’t know, I’m not big on solar powered things as they never seem to be that powerful in regards to the charge time to actual use ratio.

Etón Corporation, creator of innovative products empowered by nature, announces the Mobius rechargeable battery case with solar panel. Designed for the iPhone 4, the rechargeable battery case features a high-efficiency monocrystal solar panel that needs only one hour in the sun to provide an additional 25 minutes of talk time.

“We have perfected the use of solar power to efficiently charge electronics and Mobius is a shining example of this innovation.”

“We first previewed the Mobius at 2011 International CES to rave reviews and we are proud to officially announce the product to the masses,” says Esmail Hozour, CEO of Etón Corporation. “We have perfected the use of solar power to efficiently charge electronics and Mobius is a shining example of this innovation.”

Differentiating itself from solar-charging solutions on the market today, Mobius features a quick charge time and the ability to store charge until you need it. The high-efficiency monocrystal solar panel re-charges the 1800 mAh Rechargeable lithium ion battery pack on the back of the case. Only one hour of solar charging provides an additional 25 minutes of talk time, 20 minutes of internet use, 35 minutes of video playback and more than two hours of audio playback. Mobius can also be charged via the included Micro-USB cable and will sync with iTunes for maximum convenience. Once the battery has been re-charged, the user is in control as to when the extra battery power is used. Mobius features a standby switch to turn off direct power transfer to the iPhone 4, allowing the case to charge and store energy in its own battery – only using the power when you need it.

The durable and ergonomic battery case has both a battery charge and solar charge indicator, so the user always knows the power status of the Mobius. Weighing only 3.4 ounces, Mobius also features a USB connection to charge the battery via computer, as well as the unique and proprietary snap fit design protects the glass on the back of the device.

Mobius is available at Amazon.com (http://www.amazon.com/dp/B005HMCNO2) and retails for $80. For more information about Mobius, the full line of Etón products or the company, visit www.etoncorp.com.
